【摘要】：现代电子通信技术的快速演进,推动着与其休戚相关的误码测试技术地不断更新发展。误码测试技术作为通信产品的重要设计测试验证手段,其测试中间结果和最终结果能有效的辅助技术人员对在研、在产的通信设备的工作可靠性、稳定性做出判别。现今通信产品早已将误码率等误码测试数据作为其自身重要的技术指标,纳入产品的设计之中。而误码测试技术作为一项重要的通信指标,在应用面上也并不仅仅限制使用语通信产品的设计验证阶段,其还能灵活的应用于通信产品后期的生产验收、安装调试和运营维护等阶段,这几乎涵盖了通信产品的整个生命周期。目前市场在产在售的通用型误码测试仪,具备丰富的通信测试接口,精巧的结构设计,多样化的应用功能,而广泛使用于不同的通信测试领域。但其精巧的设计和多样化的功能,需要使用者付出高昂的价格成本,同时其虽然拥有丰富的通信测试接口,但无论如何也无法涵盖所有的通信接口类型。例如针对GMSK无线数字调制信道的误码率测试需求,通用的误码测试仪在接口上就难以满足测试应用。为此,技术人员必须在通用型误码测试仪之外单独设计制作一款GMSK无线数字调制信道接口适配器以实现与通用误码测试仪的配接,这对测试人员而言通用误码测试仪在应用方式上将受限。本论文正是针对上述问题,以GMSK数字调制信道的通信产品误码测试技术为主要研究对象,在深入分析GMSK数字调制解调技术,以及当前主流的计算机通信技术的基础之上,提出了研制一款基于PCI计算机通信总线接口的GMSK调制信道误差测试仪。从经济适用性考虑,为简化用户测试环境搭建,降低开发成本,本课题大规模选用了市场上主流的电子信息技术,并借鉴成熟的开发手段和方法,在硬件设计上采用DSP数字信字处理器和CPLD复杂可编程逻辑器件作为嵌入式系统核心控制模块,设计实现了双通道GMSK调制解调信道接口、PCI计算机计算机通信总线接口、误码计数、数据位同步和小m序列伪随机测试码生成等功能;而在计算机应用软件设计上采用C++Builder 5.0集成软件开发环境,设计实现了误码测试流程控制、误码统计、误码率计算和人机交互。
[Abstract]:The rapid evolution of modern electronic communication technology promotes the development of error test technology which is closely related to it. As an important means of design and verification of communication products, error test technology can effectively assist technicians to judge the reliability and stability of communication equipment in production and research. Nowadays, the error test data such as bit error rate (BER) has been taken as an important technical index in the design of communication products. As an important communication index, error code testing (BER) is not only limited in the design and verification stage of communication products, but also can be applied to the acceptance of communication products in the later stage. Stages such as installation, commissioning and operational maintenance cover almost the entire lifecycle of the communications product. At present, the universal error-code tester, which is on sale in the market, has rich communication test interface, exquisite structure design and diversified application function, and is widely used in different communication test fields. But its exquisite design and diversified functions require users to pay a high price cost, and although it has a wealth of communication test interfaces, it can not cover all types of communication interfaces in any way. For example, in order to meet the requirements of GMSK wireless digital modulation channel BER test, the universal BER tester is difficult to meet the test application in the interface. Therefore, the technicians must design and manufacture a GMSK wireless digital modulation channel interface adapter in addition to the universal error code tester to realize the connection with the universal error code tester. This will limit the way in which the universal error-code tester is applied to testers. Aiming at the above problems, this paper takes the error code testing technology of GMSK digital modulation channel as the main research object, based on the in-depth analysis of GMSK digital modulation and demodulation technology, as well as the current mainstream computer communication technology. A GMSK modulation channel error tester based on PCI computer communication bus interface is developed. Considering the economic applicability, in order to simplify the construction of user test environment and reduce the cost of development, this paper selects the mainstream electronic information technology in the market on a large scale, and draws lessons from the mature development means and methods. In hardware design, DSP digital word processor and CPLD complex programmable logic device are used as the core control module of embedded system. The dual-channel GMSK modulation and demodulation channel interface and PCI-based communication bus interface are designed and implemented. The functions of data bit synchronization and pseudorandom test code generation of small m sequence, and the design of computer application software using C Builder 5.0 integrated software development environment, designed and realized the error test flow control, error code statistics, Error rate calculation and man-machine interaction.
